Abstract:
As environmental regulation is being enhanced in China, the coal industry has established zero discharge of wastewater as a target. The management of mine brine wastewater has become a great challenge to coal chemical industry. The deep well injection has been considered as a state of the art technology with long-term technical experience and well-designed management system for the treatment and disposal of high-saline wastewater in the United States. The US EPA listed the deep well perfusion (injection) as a safe and reliable wastewater terminal treatment and disposal technology. This paper reviewed the technical characteristics, policy and regulation, and the application of deep well injection technology internationally, and discussed the feasibility on the treatment and management of mine brine wastes in China.
